appii'eatioa and December 1, i913. seriai No. 803,897-4 Be it known thatwe, FRANieSrRaNGaa and NICHOLAS M. Srnaifvoan, citizens of the UnitedStates of America, residing at Detroit, in the county of-Wayne and-Stateof Michigan, have invented ="c'ertainf.'new"ind useful Improvements inlVheel-Hubs, 'of which vthe following is a specificationg'referencebeing had therein to the accompanyingdrawings. l

his-invention relates to a demountable hub for wire automobile wheels,and the objects of our invention are to provide an antifrictional hubthat is mounted upon an axle in a manner, as hereinafter set forth, thatpermits of iii-wheel being'removed from the axle without...disassembling the anti-frictional bearings thereof, and to providea'wheel hub that is positively locked. relatively to the axle bearingsupportthereof.

The -above and otherA objects.. are attained by a strong andd'l'irablemechanical construction con'sistiiig of-'comparativ'el"A few; parts thatare Aeasy to, assern le and ighly efficient for automobile wheels. .Y

The invention will be hereinafter specifically described and thenclaimed, and reference will now be had tothedrawing, wherein there isillustrated a preferred embodiment of my invention, but it is to beunderstood that the structural elements are susceptible to such changes,as in the size, sha and manner of assemblage as fall within the scope ofthe appended claims.

The balls 8are/retained in engagement with the collars 5 and 6 by Vouter collars 9and 1 0. having ball races l1. Any suitable 'means can be resorted tojfor placingthe anti-,friction balls between thecollar's, for stance larsand plugged after through openings formed in the?liter eol-v the ballsare placed therein. i

Surrounding the end of the axle is a tapering sleeve 12 that tapers fromthe inner vend thereof to the outer end. The sleeve 12,

adjacent to'l the ends thereof, hasann'ular interior flanges 13, one ofsaid flanges pro` viding a seat for the Collars and fla-nd the otherflange providing a seat for the collar i 10. The pairs of collars retainthe sleeve 12 out of engagement with-the axle,l, and the inner end ofthe sleeve is provided with radially disposed Vequally spaced' lugs,the( purpose of which will hereinafter appear. The outer end of thesleeve 12 terminates inan exteriorallyrscrew -threadd cylindrical lportion 15 accommodating the 'nu 1 can be placed ther M by the!"

The crown/'end 19 of the hub vmembeip'l? is cutaway to provide anannularA recess 22 which provides clearance for the nut/"16 employed toretain the hub member "17 upon.
